Upon inquiry by University, Licensee will provide any requested assurances and disclosures, including, but not limited to, financial records that will demonstrate its financial capability.

7.0 Patent Prosecution and Cost Recovery

7.1 Patent Prosecution. [***] will have sole control over the filing, prosecution, maintenance, and management of any and all issued patents and pending and future patent applications encompassing the Licensed Patents, as of the Original Effective Date; provided that [***] will identify in writing to [***] countries (“Identified Countries”) in which to file, prosecute, and/or maintain patent applications or patents of the Licensed Patents. [***] will select all outside counsel for prosecution of the Licensed Patents, which counsel shall be reasonably acceptable to [***], and such counsel will represent [***] in such prosecution. [***] will keep [***] fully informed, at [***] expense, of all prosecution related actions, including submitting to [***] copies of all official actions and responses, and will reasonably cooperate with [***] to whatever extent is reasonably necessary to provide [***] the full benefit of the license granted herein. Each party will promptly inform the other as to all matters that come to its attention that may affect the preparation, filing, prosecution, or maintenance of the Licensed Patents and permit a reasonable amount of time for each other to provide comments and suggestions with respect to the preparation, filing, and prosecution of Licensed Patents, which comments and suggestions will be considered by the other party. All reasonable comments provided by [***] will be reasonably incorporated by [***]. [***] shall not abandon any of the Licensed Patents without the prior written consent of [***].

7.2 Non-Identified Countries. At [***] option, in countries other than the Identified Countries (“Non-Identified Countries”), [***] may prepare, apply for, seek prompt issuance of, and maintain during the term of this Agreement patent application and patents encompassing the Licensed Patents using patent counsel selected by [***]. The preparation, prosecution, filing and maintenance of all patents and patent applications contained in the Licensed Patents in Non- Identified Countries shall be the primary responsibility of [***]. License grants referred to in Article 3.0 of this Agreement shall not apply to such patents and applications. At the request and expense of [***], and at the [***] sole discretion, [***] may advise [***] with regard to any actions taken with respect to the Licensed Patents in a Non-Identified Country.

7.3 Patent Fee Reimbursement. [***] will reimburse [***] for all fees and costs relating to the filing, prosecution, and maintenance of patent applications relating to Identified Countries, including without limitation, interferences, oppositions, and reexaminations, and the maintenance and defense of patents in Licensed Patents, including fees and cost incurred and invoiced prior to (as stated in Appendix D according to clause 7.3.1), on, and after the Original Effective Date. Such fees and costs will not include costs incurred by [***] in the use of its own resources, such as employee time, and will not extend to patenting fees and costs incurred by [***] after termination of this Agreement. Unless otherwise specified in Appendix D, [***] will pay invoices for such fees and costs submitted by [***] upon receipt of any such invoice. In any country where [***] fails to pay fees and costs invoiced to [***] by [***] within [***] of the date of such invoice and does not remedy such payment failure within [***] from written notice by [***] to [***] to this effect, [***] may file, prosecute and/or maintain a patent application or patent at its own expense and for its own exclusive benefit, and Licensee thereafter will not be licensed under such patent or patent application.

7.3.1 Past Patent Reimbursement. Licensee will reimburse University for [***].

7.3.2. In the event that University grants or has granted any additional licenses under any of the Licensed Patents, as may be permitted hereunder, Licensee shall thereafter only be responsible to pay a portion of such fees and costs relating to any Licensed Patents accruing during the period in which such additional licenses are effective, calculated by multiplying such costs and expenses by a fraction, the numerator of which is [***] and the denominator of which is [***]. Each time that an additional license is granted by University or lapses under any such Licensed Patent, Licensee’s responsibility for payment hereunder shall thereafter (prospectively only) be further reduced or increased in the same manner.

7.4 Election to Discontinue Licensed Patents. Licensee’s obligation to pay patent costs as specified in Article 7.3 of this Agreement shall continue for as long as this Agreement remains in effect; provided however, that Licensee may terminate its obligation with respect to any given patent application or patent upon [***] written notice to University. University will use its best efforts during the [***] period to minimize any additional patent costs upon receipt of notice from Licensee. University may elect to file, prosecute, and/or maintain such applications(s) or patent(s) at its sole discretion and expense; provided however, that Licensee shall have no further right or license regarding such patent application and related Licensed Patents.

7.5 Extension of Licensed Patent(s). Licensee may request that University have the normal term of any Licensed Patents extended or restored under a country’s procedure of extending patent term for time lost in governmental regulatory approval processes, and the expense of doing so shall be borne by Licensee. Licensee shall assist University to take whatever action is necessary to obtain such extension. In the case of such extension, royalties pursuant to Article 8.0 shall be payable until the end of the extended life of the patent. Licensee shall have the sole decision-making authority whether to effect the extension of such patents but will reasonably factor University’s input into any such decision.

8.0 Licensing Fees and Royalties

8.1 Upfront License Consideration. Holdings issued to University [***], satisfying in full the obligations under Section 8.1 in the Prior Agreements.

8.2 Patent Cost Reimbursement. In addition to the foregoing Upfront License Consideration, Licensee will reimburse University for (i) [***]; and (ii) [***].

8.3 Minimum Annual Royalties. During the term of this Agreement, Licensee agrees to pay Minimum Annual Royalties according to the following schedule; such Minimum Annual Royalties are due in full and payable on January 1^st of each year and are creditable against Earned Royalties on a non-cumulative basis which are due and payable in the same year.

[***]

8.4 Earned Royalties. During the term of this Agreement, Licensee agrees to pay to University [***]% of the Net Sales Revenue up to cumulative Net Sales Revenue of [***] and [***] % of the cumulative Net Sales Revenue above [***] for Licensed Product(s) sold by Licensee and its Sublicenses (the “Earned Royalty”). Earned Royalty payments are due and payable within [***] of the end of each calendar quarter.

8.4.1 Stacking of Earned Royalties. In the event Licensee reasonably determines that it is required to obtain one or more licenses from any third party in order to develop, use or commercialize a Licensed Product, then Licensee may offset up to [***] percent ([***] %) of the Earned Royalties due to University pursuant to Article 8.4 for sale of a Licensed Product based on the royalties actually paid to the third-party. In no event shall Earned Royalties payable under Article 8.4, as the case may be, be reduced by more than [***] percent ([***] %) of such Earned Royalties as would otherwise be due.

8.5 Sublicense Payments. Except with regard to Sublicenses granted by Licensee to Affiliates Licensee agrees to pay to University:

[***]

“Sublicensing Non-Royalty Revenue” means all cash and non-cash considerations received from Sublicensees for Sublicenses granted by Licensee to and in Licensed Patents (except for Sublicenses to Affiliates), excluding royalties or profit share payments which correspond to royalties paid pursuant to Article 8.4, loans, equity investments, reimbursement of patent expenses and research and development support.

For clarity purposes, “Sublicensing Non-Royalty Revenue “ includes all upfront payments, license fees, options fees, option exercise fees, milestone payment and similar consideration paid by a Sublicensee that is not an Affiliate to Licensee as consideration for the Sublicense of the Licensed Patents; provided, however, that Sublicensing Non-Royalty Revenue shall exclude any consideration paid in connection with or related to (i) any research and development of the Licensed Products, (ii) any investments in Licensee or its Affiliates to

acquire Licensee’s or its Affiliates’ securities, and (iii) and any Acquisition of Licensee or its Affiliates. In no event shall Licensee pay Sublicense Payments to University of sub- licensing non-royalty revenue and other non-cash consideration deriving from Sublicenses to an Affiliate. Licensee agrees to pay to University the Earned Royalty rate of Article 8.4 as applied to Sublicensee’s Net Sales Revenue for Licensed Product. Sublicense payments are due and payable within [***] of the end of each calendar quarter in which such consideration is received by Licensee.

8.5.1. In the event that Sublicensing occurs prior to Milestone Payments as set out in Article 8.6, Milestone Payments shall remain payable, however no Sublicense Payment shall be payable pursuant to this Article 8.5 for any portion of payments received from Sublicensees that are in fulfillment of a Milestone paid to University pursuant to Article 8.6 hereof.

8.5.2. In the event that the Licensed Patents are sublicensed as a “bundle” with other technologies, the value attributable to the Licensed Patents will be a commercially reasonable value as determined by Licensee, providing that (a) proper documentation supporting that valuation is provided by Licensee to University, and (b) if University reasonably disputes that valuation, then in any dispute resolution the burden will be Licensee’s to support its valuation.

8.5.3. In the event that non-cash consideration in the form of a license to intellectual property rights is received as Sublicensing Non-Royalty Revenue, Sublicensing Non-Royalty Revenue shall be calculated based on the fair market value of such non-cash consideration, or, at Licensee’s election, Licensee may distribute University’s share to University in kind; provided that Licensee may only elect to make such a distribution if such non-cash consideration is a freely transferable security (except for such restrictions on transfer imposed by law). For clarity, a cross-license of intellectual property rights that are necessary for Licensee to make, have made use, have used, sell, offer for sale, have sold, export and import Licensed Products, and other routine contractual covenants that do not involve the payment of any monetary consideration and are customary in the type of transaction that the Sublicense is included in (including covenants providing for the research, development, supply, and commercialization responsibilities of the Sublicensee, confidentiality provisions, licenses or other rights or forbearances with respect to improvements and other technologies and intellectual property, retention of co-promotion rights or options to obtain co-promotion rights to the Licensed Product(s) covered by such Sublicense, and indemnification) shall not be deemed non-cash consideration. In addition, to the extent that Licensee enters into a cross-license with a third party to achieve freedom-to-operate for Licensed Products while providing the third party with freedom-to-operate with respect to all or some portion of the Licensed Patents, the value of the licenses to Licensee as part of such cross-license, and the other routine contractual covenants by other parties to such cross-license, shall not be deemed to give rise to Sublicensing Non-Royalty Revenue for purposes of this Agreement. In addition, no change of control transaction shall be deemed to be a Sublicense nor to give rise to Sublicensing Non-Royalty Revenue hereunder.

8.6 Milestone Payments. Licensee agrees to pay University the milestone payments per Licensed Product as set forth below:

[***]

Licensee must notify University in writing within [***] upon the achievement of each Milestone, such notice to be accompanied by payment of the appropriate Milestone Payment.

8.7 No Royalty Deductions for Charges Imposed. Licensee will be responsible for the payment of all taxes, duties, levies, and other charges including, but not limited to sales, use, gross receipts, excise, VAT, ad valorem and any other taxes, any withholdings or deductions, import and custom taxes, any duties, or any other charges imposed by any taxing authority with respect to the royalties payable to University under this Agreement. Should Licensee be required under any law or regulation of any government entity or authority, domestic or foreign, to withhold or deduct any portion of the payments on royalties due to University, then the sum payable to University must be increased by the amount necessary to yield to University an amount equal to the sum it would have received had no withholdings or deductions been made. University will cooperate with Licensee in the event Licensee elects to assert, at its own expense, University’s exemption from any such tax or deduction.

8.8 No Duplication of Royalty Payment Due to Licensed Patents. No multiple royalties will be payable to University because any Licensed Product or its manufacture, use, or sale are or will be covered by more than one patent application or issued patent included as part of Licensed Patents.

8.9 [***] License Fee. Upon the written request of Licensee, University will negotiate in good faith with Licensee for [***].

The royalties on sales in currencies other than U.S. Dollars must be calculated using the appropriate foreign exchange rate for such currency quoted in The Wall Street Journal on the last business day of the calendar quarter in which the Net Sales Revenue occurred. All non-U.S. taxes related to royalty payments must be paid by Licensee and are not deductible from the payments due University.

9.2.3 Late Fee. Any payment due to University under terms of this Agreement that is more than [***] past due shall bear interest until paid at a per annum rate equal to [***] percent ([***] %) as set forth by The Wall Street Journal on the date on which such payment is due. The payment of such interest amount must be made at the time the overdue payment is made. The payment of such interest amount will not foreclose or limit University from exercising any other rights it may have as a consequence of the lateness of any payment.

10.0 Record Keeping

10.1 Records. Licensee, its Affiliates, and Sublicensees, must keep complete and accurate records and books of account containing all information necessary for the computation and verification of the amounts to be paid hereunder.

Licensee will, at the request of University, permit one or more accountants selected by University (“Accountant”) to have access to Licensee’s records and books of account with a reasonable notice during ordinary working hours to audit with respect to any payment period ending prior to such request, the correctness of any report or payment made under this Agreement, or to obtain information as to the payments due for any such period in which the Licensee failed to report or make payment pursuant to the terms of this Agreement.

University shall ensure that the Accountant is bound by similar confidentiality as obligations as apply to University according to Article 5.

10.4 Audit Findings. Should the Accountant believe there is an inaccuracy in any of the Licensee’s payments or noncompliance by the Licensee with any of such terms and conditions, the Accountant will have the right to make and retain copies (including photocopies) of any pertinent portions of the records and books of account.

Both parties shall use reasonable efforts and cooperation to terminate infringement without litigation.

15.2 Rights to Sue for Infringement. Pursuant to this Agreement and the provisions of Chapter 29 of Title 35, United States Code, [***] may a) bring suit in its own name, at its own expense, and on its own behalf for infringement of presumably valid claims in the Licensed Patents and defend in its own name, at its own expense, any allegation of invalidity or non-infringement of any of the Licensed Patents brought in a declaratory judgment action or raised by way of counterclaim or affirmative defense in an infringement suit brought by the [***]; b) in any such suit, enjoin infringement and collect for its use damages, profits, and awards of whatever nature recoverable for such infringement; and c) settle any claim or suit for infringement of the Licensed Patents.

In the event that [***] percent ([***] %) of such expenses exceed the amount of Earned Royalties payable by Licensee in any calendar year, the expenses in excess may be carried over as a credit on the same basis into succeeding calendar years. A credit against litigation expenses, however, may not reduce the royalties due in any one year to less than the Minimum Annual Royalties set forth in Article 8.3.
